(under subclass 271) Device wherein the vessel is provided with a wing-like member mounted so as to coact with the atmosphere to generate a lifting force, when the vessel is in motion, which tends to raise the vessel out of the water.
(1) Note. The vessels found herein are always more or less waterborne and the airfoil merely tends to reduce the amount of hull below the waterline, thus, seaplanes and like aeronautic devices will generally not be found herein.
